ELECTROMEDICAL DEVICE.

SPECIFICATION forming part of Letters Patent No. 684,225, dated October8, 1901.

Application filed March 6, 1901.

T0 aZZ whom i0 new/ concern:

Be it known that I, GEORGE GRAYBILL, a citizen of the United States,residing at York, in the county of York, State of Pennsylvania, haveinvented certain new and useful Improvements in Electromedical Devices,of which the following is a specification.

The presentinvention relates to improvements in electromedical devices.

It is well known that if an electric current is passed through anelectrode containing a medicinal preparation the beneficial effects ofboth the current and medicament will be simultaneously applied to thebody against which the electrode is placed.

The object of the invention is to provide such an electrode, in which arelatively large proportion of the medicinal liquid will be exposed tothe action of the electric current.

\Vith this object in view my invention consists in the peculiarconstruction and arrangement of parts, which will be hereinafterdescribed.

In the accompanying drawings, Figure l is an elevation of a deviceembodying my improvements. Fig. 2 is a longitudinal sectional view ofthe same, and Fig. 3 is a transverse sectional view taken on the line 000c of Fig. 2.

Referring to the drawings, A designates a tubular body or container madeof any suitable non-conducting material, preferably of glass. This bodyis provided at its ends with detachable caps or heads B C, which may besecured to the body A inany suitable manner. As shown, the tube A isprovided at its ends with bands or sleeves D, the exterior surfaces ofwhich are suitably threaded and are engaged by internally-threadedflanges formed on the heads B G. The head B is provided with a centralaperture that eommuni-- cates with a passage in a stem F, which may beformed integral with or suitably secured to the head. A valve G isprovided in said stem for controlling the passage of liquid from thebodyA through the duct or passage therein.

To the outer end of the stem F is detachably connected the head of theelectrode, which may be made in any of several forms. The one shownconsists of an apertured disk H, provided on its outer face with asponge Serial No. 50,028. (No model.)

or other absorbent pad I. The disk is so connected with the stem F thatwhen the valve G is opened liquid from the bodyA will pass to theabsorbent pad I As shown, it is provided with a tubular support J, whichis of such diameter that the end of the stem F will enter and fit snuglytherein. As stated, the electrode-head is preferably made separate anddetachable from the stem F, so that it can be easily removed and anothersubsti tuted, if desired. In some cases it maybe preferable to employ ahypodermic needle or similar device instead of the form ofelectrode-head herein illustrated and above do scribed.

A binding-post K is secured in the head 0 and adapted to have connectedthereto one of the wires of an electric circuit; Said post is providedwith a shank or body that extends through the head in which it ismounted, and to the inner end of the shank, within the body A, iselectrically connected one end of a conductor L. The latter, preferablya plati num wire, is made in the form of a coil, so as to provide alarge contact surface on a relatively short conductor. Preferably it isof the spiral form illustrated. It does not extend the entire length ofthe tube A, but terminates within a short distance of the head B. At itsfree end the spiral conductor L is enlarged into or otherwise providedwith a disk M.

A suitable quantity of the desired medicament, preferablyi'n liquidform, is introduced into the body A, the head H attached, and thebinding-post K connected to one of the wires of an electric circuit.

Then the device is not in use, the valve G is turned to prevent theescape or passage of liquid through the d not E.

In using the appliance the yielding pad I is applied to the surface tobe treated and another electrode connected with the other wire of theelectric circuit is also placed in contact with the body in the usualmanner. When the valve G is'turned to open the duct E, liquid will flowfrom the holder A to the absorbent pad I and, as will be seen from thedrawings, the liquid flowing through said duct will be exposed to theaction of the electric current.

The head 0 is preferably made of insulat ing material and the other headB and stem F connected therewith may be formed of similar material, orin case it is preferred to make the last said parts of metal the plate Hmay be insulated from the stem F, to which it is connected in anysuitable manner. For example, as shown in Fig. 2, the tubular support Jmay be insulated from its plate H by a non-conducting sleexe or washerN.

The electric current passes through the coiled conductor L, which by itsform exposes a large portion of the liquid in the holder A to the actionof the current. As the said conductor does not extend the entire lengthof the bodyA the currentis caused to pass through the body of the liquidsituated between the end of the conductor and the adjacent head B,andthe liquid absorbed by the pad I is also subjected to the action of thecurrent. ThusI am enabled to simultaneously apply to the body with whichthe pad I contacts both liquid medicament and electricity. It will alsobe noticedthat by employing a conductor of coiled form I am enabled toobtain a large amount of contact surface within a relatively shortdistance. This enables me to make the entire device compact and of suchform that it will occupy but little space.

Having thus described my invention, what I claim, and desire to secureby Letters Pata valved outlet, and a conductor of coilforrn.

arranged within said container and extending from a point near theoutlet therein to a" binding-post supported by the container.

2. A device for the purpose described,con-

sisting of a tubular body of non-conducting material, detachable headsclosing the ends .7 of said body, and one of which is provided with anoutlet opening or passage, a bindingpost secured in the other of saidheads, and

a conductor electrically connected at one end with said binding-post andextending toward the outlet in the opposite head, said conductor beingof less length than the distance between said heads.

In testimony whereof I affix my signature 7 in presence of twowitnesses.

GEORGE GRAYBILL.
